LINOTYPE AND OTHER TYPE-CASTING MACHINE.

To all whom it may concern:

Be it known that IfGHRISTIAN A. AL- BRECHT, a citizen of the United States, and resident of Baltimore, in the State of Maryland, (whose post-office address is 677 C0- chines, of which the following is a specification.

As is well known, the matrices with two or more superposed intaglio letters for linotype or other type-casting machines are vertically adjusted, before they together with the space bars are pushed'into the known vertically movable yoke, which then lowers and presents the meanwhile clamped line of matricesand space-bars to the mold or moldwh'eel'for the casting of the linotype. Afterwardsthe yoke rises and applies the loosened line of matrices and space-bars to the. known rail or other machine part into which the line is pushed, so that the matrices may be sepa rated from the space-bars by means of the movable distributor or the like and transferred to the top of the machine to be there distributed to the magazine or magazines. The yoke is usually provided with a laterally movable part having one orseveral horizontal ledges, on which the respective matrices,

if raised, are made to rest with their lower rear'ears or lugs and to slide. When the yoke is raised, some means is provided on the machine for withdrawing the said movable .part, so that the raised matrices are released and permitted to drop, until they rest with their'upper ears or lugs on stationary ledges or shoulders in the yoke. Then all the various matrices in the yoke will be on the same level, so that they can be pushed into the said rail or other machine part for engaging the teeth of the movable rail. However, as

the matrices constantly and repeatedly drop and strike various machine parts, their lower ears or lugs are rapidly worn. away, more particularly on the external points, so that the correct position of the several raised matrices for the casting operation is no longer insured.- To remed this defect, it has been proposed to provi e the matrices on the rear edge with a nose, so that they in their raised position may be supported on two places,

" ,Y1Z., ,on the said nose and on the lower rear Specification of Letters Patent. Application filed November 27. 1907. Serial No. 404.125.

ear or lug. However, the said noses are ob: jectionable for two reasons. The one reason is, that they would require the various channels in the machine parts, through which they pass, .to. be altered; and the other reason is, that in linotypemachines they would not pass through the ordinary matrix-delivering mechanisms in the magazines.

My invention relates to improvements in matrices with two or more intaglio letters and in the vertically movable yoke, whereby the wear and tear of the lower ears or lugs of the matrices is reduced. The objects of my improvement are, first, to provide each matriX with a recess on the rear edge, preferably in the rear upper ear or lug; second, to provide in the yoke a second laterally movable rail; and, third, to provide means for simultaneously withdrawing the two rails on the yoke reaching its uppermost position. I will now roceed to describe my invention with re erence to the accompanying drawing, in which Figure 1 is a vertical cross section through a vertically movable yoke applied with the matrices to the mold on a mold-wheel, the matrices being each provided with two intaglio letters and two of them being shown in different positions, and Fig. 2 is a vertical recess k (see Fig. 1) in the upper rear ear or V lu as shown. In the vertically movable yo e a I provide besides the known rail e a second rail Z, which is adapted to engage in the recesses 7c of the matrices, so that each raised'matrix b is guided on two places, viz. with the lower rear ear or lug c on the shoulder (1 of the lower rail e and with its upper rear ear or lug on the'ledge on the-upper rail Z. I combine the two rails e and Z together by means of a vertical part m which is pro v ded with a hook n. Suitable recesses are provided in the-yoke a for guiding the'two rails e and [in the cross direction. A two- .armed lever o p. rocking on a pin 9 is provided infla recess of the yoke a, andit's lower "arm ois'made to engage in the hook 7 while arranged to be depressed forsimultaneously 55 tically movable yoke ada ted to, normally its u er arm is normallypressed outwards 1 (see ig. 1) by a helical spring 1-, which is attached to some projection (not shown) on the 'yoke', so, that the two rails e and I normally projectinto the path of the matrices 6 b During the operation of the machine some of the matrices (denoted by b) are in any- -known manner shifted into the upper position, while the other matrices b may oc- -cupy their normal position. 1 When after the assemb the'line of matrices and s acebars is pus ed into theyoke a, and the atter lowers and a lies the meanwhile clamped line. to the mOlii 'w (Fig. 1) on the mold-wheel,

" the upper inta lio letters of the not raised matrices b an the'lower intaglio letters of the raisedmatrices'b will be opposite-to the slot of the mold w, so that the hnotype can be cast. v

The upper end of the arm p is so shaped as 'to form a cam is, which is beveled off, so that on the-yoke a reaching its up ermost position i the cams strikin a suitable edge '0 on a slide u or the like wil be depressed and thereby the two rails e and 1 W111 be withdrawn to release the raised matrices b, which will then drop and be on the same level as the other matrices b, all of them, resting with their upper ears or lugs on the two shoulders h of t e parts 'i, and i of'the yoke a. In this position the matrices are ready to engage the teeth of the movable rail t in order to be may be rep aced by separated from the space-bars during their transfer to the top of the machine.

Y I do not bind'myself to the construction shown of the arts u, c and tin-Fig. '2, as they arts .of someother known linot pe or ot er type-casting machine of a di' erentcon'structlon. The essential point is, that'the cam s on the lever 0 p be withdrawing the two .rails e and l. The
